i ROD-COUPLING. i

Specification of Letters Patent.

Patented Jan. 8, 1907.

Application filed March 2, 1906. Serial No. 303,933.

To all whom it may concern.-

Be it known that I, CHARLIE A. ANDER- soN, a resident of Cornplanter, inthe county of Warren and State of Pennsylvania, have invented certainnew and useful Improvements in Rod-Couplings; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in rod-couplings, and moreparticularly to an improved coupling for sucker-rods, pumprods, and thelike, the object of the invention being to provide an improved couplingwhich will permit the rods to be readily and quickly secured togetherand which will firmly secure them when once coupled and the inventionconsists in certain novel features of construction and combinations andarrangements of parts, as will be more fully hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation,illustrating my improvements. Fig. 2 is a view in longitudinal section.Fig. 3 is a view in cross-section, and Figs. 4 and 5 are views of theparts separated.

1 and 2 represent the two rods which constitute the two members of thecoupling. Member 1 is made with-a cylindrical bore from its end to arecess 3, and member 2 is made with a pin 4.- to enter'the bore ofmember 1. The pin 4 is rovided at its end with a key 5, movable t rougha keyway 6 in member 1 which communicates with the bore of member 1 andalso with the recess 3 in said member. When the key 5 reaches the recess3, the member 2 is turned, and the key 5 will move through the recessand rest against the end wall thereof, out of alinement with the keyway6, thus preventing separation of the members until the pin is againturned to aline its key 5 with keyway 6. The

- key 5 is of a length approximately the same as the width of recess 3,so that it will have practically no longitudinal movement therein andthe members 1 and 2 will be held tightly together.

To retain the pin in locked position, a gate 7 is provided to close thatportion of the recess between'the key 5 and the end of the recess, andthis gate has a lug 8 at one end hinged in a pocket in member 1 by a pin9. Aspring-band 10 is secured to the outer face of gate 7, and when thegate is closed this spring-band rests in grooves in key 5 and member 1and is provided with a hole near its free end to receive a lug or pin 11on member scribed without departing from my invention, and hence I donot restrict myself to the precise details set forth, but considermyself at liberty to make such slight changes and alterations as fairlyfall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A rod-coupling comprising two members, one of said members having abore and an openrecess communicating with one end thereof, said memberalso having a keyway communicating with said bore and recess, the othermember provided with a pin to enter the bore of the first-mentionedmember, a lateral key on said pin to pass through said keyway and enterthe open recess, and a hinged gate to enter said recess and confine thekey therein, out of alinement with the a longitudinal bore communicatingwith the recess, said bore also having a keyway there- I00 in, a pin onthe other member to enter the bore, a key on the pin to move through thekeyway in the other member into the recess l I In testimony whereof Ihave signed this and movable in the recess out of alinelnentspecification in the presence of two subscrib- With the keyway, a hingedgate in said recess ing Witnesses.
